It gives each organelle in the cell its own specific function
Lewis structure, which shows bonding electron pairs as Lines and any nonbonding electrons as dots.
A chemical bond is holds atoms collectively in molecules. Bonds get up from the electrostatic forces between definitely charged atomic nuclei and negatively charged electrons.
Lewis symbols to describe valence electron configurations of atoms and monatomic ions. A Lewis image consists of an elemental image surrounded by way of one dot for each of its valence electrons: parent 1 suggests the Lewis symbols for the factors of the 0.33 length of the periodic table.
Lone pairs are discovered in the outermost electron shell of atoms. They may be diagnosed with the aid of using a Lewis shape. Electron pairs are therefore taken into consideration lone pairs if two electrons are paired however aren't utilized in chemical bonding.
It is representation of the valence shell electrons in a molecule. it's far used to expose how the electrons are arranged round individual atoms in a molecule. Electrons are shown as dots or for bonding electrons as a line between the two atoms.

The equation ΔHsoln = ΔH1+ΔH2+ΔH<span>3 means that either the solution is endothermic (</span>ΔH < 0, the resulting reaction is cold) or exothermic (ΔH>0, the resulting reaction is hot). The lattice energy can be solve through this equation,
<span>lattice energy = </span>ΔHsolvation - IMF - ΔHsoln<span>

Answer:
1. a) 0,18
2. e) The reaction proceeds to the left, forming more BrCl(g).
Explanation:
1. In a gas reaction as:
2SO₂(g) +O₂(g) ⇄ 2SO₃(g)
it is possible to convert kp to kc using:
kp = kc (RT)^Δn
Where kp is gas equilibrium constant, kc is equilibrium constant (13), R is gas constant (0,082atmL/molK), T is temperature (900K), and Δn is number of moles of gas products - number of moles of gas reactants (That is 2 - (2+1) = -1). Replacing:
kp = 13×(0,082atmL/molK×900K)^-1
<em>kp = 0,18</em>
<em></em>
2. Based on Le Chatelier's principle, the change in temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system. For the reaction:
2 BrCl(g) ⇄ Br₂(g) + Cl₂(g).
The addition of 0,050M of each compound cause <em>the reaction proceeds to the left, forming more BrCl(g)</em> because based on the reaction, you need two moles of BrCl per mole of Br₂(g) and Cl₂(g) to keep the system in the same. But you are adding the same proportion of moles of each compound.
I hope it helps!
